verifying aka 2 liter plus dual questions

hey guys, i recently purchased what i told was an aka 2 liter plus dual regulator from a website. It did come with the Hi pressure spring as well as the one installed.

however my question is, is the body doesnt match the one listed on the website. The logo only says aka and does not show the "2 liter +" it also does not have the extra milling on the bottom half of the body. Does this mean its only the 2 liter with an extra spring??? or did they come with different bodies and generations of the 2 liter plus?

The 2-Liter had an adjustable output pressure range of 0-350psi max and due to the popularity of the AKA brand, and the fact that some markers required regulators to output more than 350psi to function, AKA later redesigned the 2-Liter to accept a low pressure and high pressure spring pack. This new 2-Liter was called the 2-Liter+(plus) and replaced the original and diet series.

Purely cosmetic, with the "+" version introducing different spring packs.

as far as im aware, theres no changes between a 2liter plus, and a first run 2 liter plus. the later 2 liter +'s introduced the extra spring. which im almost positive you could even put in a regular 2 liter and it will behave as advertised..

no if anything, you got one of the first run 2liter+ if its looks like a 2 liter+ its a 2 liter +
